Sansevieria plant named &#39;SUPSAN1301&#39;

ABSTRACT

A new and distinct  Sansevieria  cultivar named ‘SUPSAN1301’ is disclosed, characterized by unique plant form, rosette leaf arrangement, and leaves that change from cylindrical to less terete as they mature. The new variety is a  Sansevieria,  typically produced as an indoor ornamental plant.

LATIN NAME OF THE GENUS AND SPECIES

Sansevieria aeethiopica×cylindrica

VARIETY DENOMINATION

‘SUPSAN1301’

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Sansevieriaaeethiopica×cylindrica. The new variety is the product of a plannedbreeding program, originating as a seedling from the open pollination ofan unpatented, unnamed, proprietary seed parent Sansevieria aeethiopicawith an unknown, unpatented, proprietary pollen parent variety ofSanservieria.cylindrica. The actual pollen variety is unknown becausethe cross was made by means of open pollination process in a nurserywhere several proprietary hybrids of Sanservieria.cylindrica werepresent. Any of the present hybrids could have acted as the pollenvariety. All aforementioned Sanservieria cylindrica hybrids were createdby the breeder and never commercially introduced or published andtherefore do not have a variety name. The open pollination took place in2003.

The new variety was first observed by the inventor, ThumrongSuphachadiwong, a citizen of Thailand, in 2005 after planting as aseedling in 2004 in a research greenhouse belonging to the inventor inChonburi, Thailand. After identifying the new variety as a potentiallyinteresting selection, the inventor continued confidential testing andpropagation of ‘SUPSAN1301’, assessing stability of the uniquecharacteristics of this variety.

Asexual reproduction of the new cultivar ‘SUPSAN1301’ was firstperformed at a research greenhouse belonging to the inventor inChonburi, Thailand by leaf cuttings of original plant in 2005. Access toall plants was restricted, as plants were kept in a greenhouse not opento the public, belonging to the inventor, and not accessible to thepublic. Through subsequent propagation, more than 8 generations havebeen reproduced, which have shown that the unique features of thiscultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SUPSAN1301’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘SUPSAN1301.’ These characteristics incombination distinguish ‘SUPSAN1301’ as a new and distinct Sansevieriacultivar:

-   1. The young leaves of the candidate variety have a more cylindrical    shape and as they mature, the form gradually changes from    cylindrical to less and less terete.-   2. Shape of plant; leaves arranged more as a rosette, rather than    arranged in as a fan shape, or spiral which is common for    Sanservieria.cylindrica varieties.-   3. Growth habit of the plant is unique as a whole.

PARENT COMPARISON

Plants of the new cultivar ‘SUPSAN1301’ are similar to the seed parent,the unpatented, unnamed, proprietary Sansevieria aeethiopica in mosthorticultural characteristics. However the new variety, ‘SUPSAN1301’differs from seed parent in the following characteristics:

-   1. Leaves much longer and pointy, thicker in caliber and much more    terete to cylindrical. Mother variety; leaves much flatter, shorter    and broader.-   2. More heavily branched, leaves arranged in a more rosette like    way.-   3. Taller less compact form.

Plants of the new cultivar ‘SUPSAN1301’ are similar to the possible butunknown pollen parent, Sanservieria.cylindrica in most horticulturalcharacteristics. However the new variety, ‘SUPSAN1301’ differs frompossible pollen parent in the following characteristics:

-   1. Shorter leaves, less cylindrical than father variety. Leaves    mature from more cylindrical to more terete.-   2. Rosette growth form. Farther variety is of fan shape to spiraling    form.-   3. Leaf texture is smoother.

COMMERCIAL COMPARISON

There is no similar variety but ‘SUPSAN1301’ could perhaps be bestcompared with the unpatented commercial variety Sanservieria.cylindrica‘Skyline’ because the spotting of the leaf is somewhat similar. Howeverthe new variety, ‘SUPSAN1301’ differs from ‘Skyline’ in the followingcharacteristics:

-   1. Leaves have slight arch. Comparator has straight leaves.-   2. Branches very heavily. Branches produce many leaves with very    short internodes. Comparator produces long branches which have    leaves with very long internodes.-   3. More rosette form. Comparator form is more fan shaped.-   4. Very smooth leaf texture. Comparator leaf texture is coarse.-   5. Leaves are less cylindrical to terete. Comparator leafs are more    cylindrical.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

accompanying photograph in FIG. 1 illustrates in full color a typicalplant of ‘SUPSAN1301’ grown in a commercial greenhouse in Honselersdijk,the Netherlands. The plant is 40 weeks old a 12 cm circular pot. Thephotograph was taken using conventional techniques and although colorsmay appear different from actual colors due to light reflectance it isas accurate as possible by conventional photographic techniques.
